I am a HS Coach and bought this ball for some indoor winter training and friendly matches on the weekends. Will definitely have to purchase a bag of these! Low bounce, good striking, great trainer. Now I just need to find huge tennis rackets to work on our kid's upper body strength!

I use this ball for indoor gym use with a recreational group of mixed skill and experience. This ball replaces a previous one that lasted only one game before a seam split and exposed the bladder. Sports Authority quickly replaced it - no questions asked. The new ball is performing as expected so far.
